A ieeess 23 also ends inwardly from the pei'ipheiy oi he visive casing o1 pinto 1:3, and eonnnnnien'es si its inner end with he iJeoess iig the onei.' end of said recess is Cii'iven e nippie 25, on 'he portion of seid 2 'pple piojeo'ing beyond the valve casing seemed the inner end of a. iexibie Luhe 241. .Said niie een oonnc to the valve easing', so that ii', can he introduced ino the inist innniioiii, any. gaseous fiuid, but, i. have here shown i@ ns nseci so introc'iuee nii' which 'is heseai by zhe exhaust in the engineE and for this pui'poso have shown the other terminal portion of the tube 24 coiled around the exhaust manifold 27. It is to be understood., however, that i do lnoi. iimii; my invenion to Jhis construction.

Since he oyiindriesi siide Valve it? moves 'pest vthe inneii en of the recess 23, it serves to regniete the passage of the gaseous Huid from seid, tube and ieeess 23 into he iecess A. it 'wiii he that the paris sie so arranged that, when the spark is ndvzineed in the propel direction, the siide unive 1") is witinh'swn, increasing Jthe How of the gaseous iinid into the i'eeess 14. and ninnifold, inni conversely7 when the spark ievey is i'enn'ded, the slide visive it?, moves inwfii'iiiy, und -eloses the innei'- end of the ifegess :i und induces ihe fion' of ihe gaseous fluid into the recess 14. To avoid 'toov great a rush of the air or other gaseous fluid into the recess 14, when the spark is advanced and the valve 12 is withdrawn, the inner end 28 of said valve is reduced in diameter and is also slightly tapered. The cylindrical recess 14 is 'bored in the `plate l5 not only some distance past the inner end of the recess 23, lbut through those of the walls 31 separating from one anotherl the small holes 22, which are in the direct line of the here. The object of the latter construction is to form mixing chambers and facilitate the admixture of the air or other gaseous fluid introduced through the iiexible tube 24 with. the combustible mixture from the carbureter.

For the same purpose, and also to assist in thoroughly mixing the air and gasolene vapor flowing fromt-he carbureter, a vhole 30 is bored from the periphery of the plate 15 at right angles to the hole l-i and is extended through those of the walls intervening between the small holes 22 which are in line with lsaid bore. The outer portion of this hole is then filled by a stopper 32 driven tight into the plate l5.

It' will now 'he seen that l have provided a device which may "be interposedin t'he inlet manifold ofA an internal combustion engine which will not only serve to regulate the admission of heated air or other gaseous -iiuid with the movement of the spark lever but will also contain a. mixing chamber and render more homogeneous., the mixture of` air and gasolene vaporiiowing from the oarbureter and also insure the thorough mixture thereof with additional heated air orl other gaseous fluid.A

I claim vl. In means for mixing a fluid wit-h the i combustibile mixture iiowing from the oarsage, a slide valve in said first passage to vary the size of *the opening between said passages.

l, f2. In means for mixing la Huid with the comfbusti'ble mixture llowin from the carbureteri tothe inlet/manifol of an internal pombustijon engine and simultaneously renslide valve.

naeaeee the outlet conduit of the carbureter and the 6l inlet end of the inlet conduit of the inlet manifold having therethrough a plurality of small holes adapted to register With said outlet and inlet conduits, also having therein a passage leading from its periphery and communicating with a plurality of said holes through their Walls and a passage leading from said periphery to said first named passage, a conduit communicating With theJ outer end of said latter passage for conducting fluid thereto, and a slide valve in said first passage to vary the size of the opening between said passages.

3. In means for mixing a fluid With the combustible mixture iowing from the carbureter to the inlet manifold of an internal combustion 4engine and simultaneously rendering said mixture more homogeneous, a plate interposed between 'the outletend of the outlet conduit of the carburetor and the `inlet end of fthe inlet cond-uit of the inlet manifold having therethrough a plurality of small holes adapted to register With said outlet and inlet conduits, also having therein a passage leading from its periphery and communicating with a plurality of said holes through their walls and a passage leading from said periphery *to said first named pas-- sage, a slide valve in said' first passage to vary the size of the opening between sai-dpassages, said plate having also a passage exterulingl transversely to said first-named passage and communicating with said small holes through their Walls.

e. ln means for mixing a fluid with the. combustible mixture iiowing from the carbureter to the inlet manifold of an internal combustion engine 'having an ignition spark shaft and ,simultaneously rendering said mixturemore homogeneous, a plate interposed betiyeen the outlet end of the outlet conduitf the carburetor and the inlet end of theinlet conduit of the inlet manifold having therethrough a plurality of small holes adapted .to register with said` outlet -110 and inlet conduits, also having therein a passage leading from its periphery and communicating With a plurality of said 'holes through their walls and a passage leadiiig from said periphery to said first named pas- 115 i sage, a slide valve in said first passage to -vary the size of the opening between said y Y passages, a' crank secured to the lower end of the ignition" spark shaft of the engine,
